To all whom 'may concern.'

Be it known that I, ELIJAH A. HOLLEN- BECK, a citizen' of the United States, residing in the county ofShelby and State of Missouri, have invented a new and useful Motor Cultivator, of which the following is a specification.

The main object of the invention is to provide an im lement frame to be attached .a well-known type, whereby the adjustments for the cultivator are carried entirely by the frame and are accessible from the seat of the tractor.

. The frame is to be rigidly attached to the tractor frame at the front and rear and one lever is designed .for each adjustment vertical or horizontal of both of the gangs simul-v taneously.

In the drawing:

Figure 1 is a side elevation ofthe tractor 1 with the frame applied, parts of the tractor being out away.

Figure 2 1s a front view of the same, and

Figure 3 is a lan. n n

Figure 4 is -a Yetail view.`

The tractor is of a well known type and is indicated by the letter T. The implement frame indicated by the letter F is yoke shaped and is rigidly secured to the rear housing of the tractor as shown at 5. Each rear end of the frame is bifurcated as at 6,

al bolt 7 passing through the ends of the yoke formed and secured by a nut.' The yokes 5 are attached near the outer ends of the housing H. The side bars S and Sof the frame F are bent inwardly ,as at 5', then extend forwardly in close relation to the tractor to rovide 'ample turning space for the front w eels.. The front ends of the side bars of the frame extend some distance in advance of the tractor to provide suiiicient space for the cultivator a justnrent mechamsm.

At the front ends of the frame a casting 8 is fitted over a projection on each side o the radiator frame and acts as a saddle for the implement frame. The frame F is held securely to the casting 8 by means of a U- bolt 9, litted over one side of the frame as at 10 and connected beyond the 'other side of the frame by a plato 11, fitted over the free' ends of the U-bolt 9 and secured in place by nuts 12.

A bracket' 13 is pivotally mounted over each side bar S, S, the brackets'extending from near the front ends of the side bars to a point adjacent the `U-bolt 9 but spaced therefrom by collars 14. Arms 15 clamped to the brackets 13 extend outwardly toform supports for the front ends of the gang cultivators 16, the arms 15 bein braced by draft members 17, secured to rackets 13 `and to the outer ends of the saidarms 15,

and are supported vertically by rods 18 described more in detail later.

A bracket'19 similarto 13 is. pivotally mounted'over each side bar S, S', in front of the rear wheels, these brackets carryin arms 20 which have vertical portions 21 an outer horizontal portions 22 suitably braced as at 22. The horizontal portions 22 carry the rear ends of the gang 16. These gangs I are raised and lowered by means of levers 23 provided with suitable latch mechanism 24 and connected by link 53 provided with compression spring 54 to the rear ends of beams 47 and 49 as at 5 5. The two arms`20 are connected by a link 25 referred to later.

An adjlsting means comprising lever 26 pivoted toframe S provided .with latch means 27 is connected by a link 28 to the cam lever 29, cam.29 being connected tot` similar cam 30 at the forward end of the frame by a link 31. The cams 29 and 30 are mounted on transverse pivots 32, 33 to 85 be moved by lever 26. The top horizontal portions ofthe cams 29 and 30 are provided with diagonal slots 34 and 35 respectively which slots are fitted over the upstandin portion 21 of one arm 20 andan integra 90 arm 36 of bracket 13. rllhis arm 36 is connected by rod 18 to the outer end of arm .15, A similar arm 36 is mounted on the other bracket 13. The two arms 36 and 36 areconnected to move together by a link 37.

By this means the lever 26 lmoves both the front and rear nsupporting structure of the gangs at the left of the frame lvertically through cam slots 34 and 35,'this movement being transferred to the o posits gan through links 25 and 37, so t. at as the le gan are raised the right gangs are lowere ,and vice versa.

, To provide for various width of rows and. for irregularities in having ra suitable latch is pivoted to the frame S and connected by link 39 to a lever 40. This lever has arms 41 and 42, connected bylinks 43, 44 to the pivoted sliding" brackets 45, 46, carried on arms 15. The 110 the Yrows the lever 38T,

48 to the outer cultivator beams 49. In this way all of the plow beams are moved outwardly or inwardly simultaneously. v

The diagonal shanks 50 have collars 5l fitted over the cultivator beams so as lto be adjustable around the beams and locked by clamp 52. This is to provide for ridges of varying slopes.

Im operation the tractor straddles one row of corn and cultivates the rows on each side.

The levers 23 are set at the proper height for normal cultivating. The lever 26 adjusts the gangs vertically, acting as a leveling device, making unnecessary a lever for each cultivator beam. T-he lever 38 adjusts the beams to the proper width. All of these levers are within easy reach of the driver of the tractor.

While details are shown to make a complete device, it is obvious that changes may be made so long as they are within the scope of the claims.

What I claim is:
